Description Usage Arguments Details Value See Also
The generalized cross-validation or GCV criterion is often used to select an appropriate smoothing parameter value, by finding the smoothing parameter that minimizes GCV. This function locates that value.
1 | lambda2gcv(log10lambda, argvals, y, fdParobj, wtvec=rep(1,length(argvals)))
|
log10lambda |
the logarithm (base 10) of the smoothing parameter |
argvals |
a vector of argument values. |
y |
the data to be smoothed. |
fdParobj |
a functional parameter object defining the smooth. |
wtvec |
a weight vector used in the smoothing. |
Currently, lambda2gcv
1. fdParobj[['lambda']] <- 10^log10lambda
2. smoothlist <- smooth.basks(argvals, y, fdParobj, wtvec)
3. return(smoothlist[['gcv']])
